Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.

The proposed device, Medical Diode Laser Hair Removal Device (PZ-606VI、PZ-BDT68-01、PZ-BDT68-02、PZ-BDT68-03、PZ-BDT68-04), is a surgical device, which is intended for hair removal, permanent hair reduction on all skin types (Fitzpatrick skin type I-VI);

The device incorporates a diode laser that emits invisible infrared laser radiation centered on a wavelength of 808 nm. According to the selective light absorption theory, the laser can be preferentially absorbed by the melanin in the hair follicle, thus achieving the purpose of permanent hair removal. Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime. Hair growth must remain stable for a certain amount of time and must exceed the entire growth cycle of the hair follicle. Permanent hair removal does not mean that all hair in the treated area is completely lost. Special cooling technology is applied simultaneously during treatment to cool the skin and protect skin.

There are 5 models included, PZ-606VI, PZ-BDT68-01, PZ-BDT68-02, PZ-BDT68-03 and PZ-BDT68-04, the five models have the same intended use, mechanism of action and principle, only the minimum values of energy density and pulse duration are different.

The Fractional CO2 Laser Machine uses a CO2 laser with the emission wavelength of 10600nm to emit focal spots through a high focus lens. The target is water in skin tissue. A certain amount of thermal stripping, more thermal coagulation and obvious thermal effect are produced at the part directly penetrated by the focal spot.

The Fractional CO2 Laser Machine has two operational modes, fractional mode and impulse mode.

• Fractional mode includes three modes: normal, random and midsplit;
• Impulse mode includes three modes: single, continuous and impulse.

The Fractional CO2 Laser Machine has 5 modules: Control display panel module, Main control power module, Light guide arm module, Fan cooling module, Laser module.

The provided FDA 510(k) clearance letter describes a "Fractional CO2 Laser Machine" (K250782) and its substantial equivalence to a predicate device, the "Ilooda Fraxis CO2 Laser" (K172096).

However, the document primarily focuses on demonstrating substantial equivalence through non-clinical performance and safety comparisons rather than detailing specific acceptance criteria for a study that proves the device meets those criteria, particularly in the context of device performance outcomes for intended use. The clearance is based on the device being as safe and effective as its predicate through these comparisons and compliance with relevant standards.

Therefore, many of the requested sections regarding the study that proves acceptance criteria (especially clinical study details, ground truth, expert involvement, and reader studies) cannot be extracted from this document as such studies are explicitly stated to be not included.

Here's an analysis of what can and cannot be extracted:

Acceptance Criteria and Device Performance (Based on Substantial Equivalence and Standards Compliance)

The acceptance criteria are implicitly met by demonstrating substantial equivalence to the predicate device and compliance with recognized safety and performance standards. The "reported device performance" is presented through direct comparison with the predicate.

Study Information (Based on the provided document)

As per Section 10, "No clinical study is included in this submission," and Section 9 "Non Clinical Test Conclusion," the device relies on non-clinical testing and substantial equivalence to a predicate. Therefore, the following sections cannot be fully addressed with the provided text for a clinical study proving acceptance criteria.

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not applicable (N/A) for clinical outcomes given no clinical study was performed. For non-clinical tests, specific sample sizes (e.g., number of units tested for electrical safety, number of samples for biocompatibility) are not detailed in this summary, but are typically defined by the referenced standards.
   • Data Provenance: N/A for clinical data. For non-clinical compliance testing, the provenance is from manufacturer-conducted tests or accredited labs demonstrating adherence to international standards (e.g., IEC, ISO).

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

   • N/A. No clinical study for which ground truth would be established by experts is described.

3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

   • N/A. No clinical study with adjudicated outcomes is described.

4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

   • N/A. Such a study would be relevant for devices involving image interpretation or AI assistance, which this laser device is not described as having.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

Crucially, there is ABSOLUTELY NO MENTION of acceptance criteria related to a study proving performance, sample sizes, expert involvement, ground truth, or MRMC studies.

The document explicitly states:

• "No clinical study is included in this submission." This means there was no study to prove the device met acceptance criteria in a clinical setting with human subjects.
• The clearance is based on "non clinical tests" to verify that the proposed device met design specifications and was substantially equivalent to the predicate device. These typically involve engineering tests, electrical safety, EMC, and biocompatibility, as listed in the "Non-Clinical Test Conclusion" section.

Therefore, I cannot provide the requested information regarding acceptance criteria and study details for proving the device meets those criteria because this information is not present in the provided document.

The document describes regulatory compliance and equivalency based on technical specifications and non-clinical testing, not on a clinical performance study with human subjects, which would typically involve the criteria you asked about (sample size, expert ground truth, MRMC, etc.).

In summary, based on the provided text, the device was NOT proven to meet acceptance criteria through a clinical performance study. Its clearance is based on demonstrating substantial equivalence to a predicate device through non-clinical testing.

The Medical Picosecond ND: YAG Laser System is a multi-wavelength, pulsed laser system designed for the treatment of benign pigmented lesions. A key feature of the device is its ability to produce multiple laser wavelengths (1064 nm and 532 nm).

I am sorry, but the provided FDA 510(k) clearance letter for the Medical Picosecond ND: YAG Laser System (PZ-6) does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria.

Specifically, the document states:

• "No clinical study is included in this submission." (Page 11, Section 8.0 Clinical Test Conclusion)
• The "Non clinical tests were conducted to verify that the subject devices met all design specifications as were Substantially Equivalent (SE) to the predicate device." (Page 11, Section 7.0 Non-Clinical Test Conclusion) These non-clinical tests relate to compliance with various IEC and ISO standards for medical electrical equipment, laser safety, and biocompatibility, as well as software validation. These are not performance acceptance criteria for the intended use (tattoo and lesion removal) in the way you are asking.

Therefore, I cannot provide the detailed information requested in your prompt as it is not present in the provided text.
